Description
Technical Field
The invention belongs to the field of insect breeding, relates to breeding of dipteran insect hermetia illucens, and particularly relates to an LED light source for promoting mating and oviposition of adults during industrial breeding of hermetia illucens.
Background
The Hermetia illucens (Hermetia illucens L.) which belongs to the Hermetia illucens of the family hermetiaceae of the order Diptera and is widely distributed in 45 degrees in northern latitude to 40 degrees in southern latitude, and is a saprophagic environmental resource insect. The hermetia illucens can complete a metamorphosis development generation within 30-40 days and passes through 5 stages of eggs, larvae, prepupa, pupae and imagoes, wherein a large amount of food and nutrition are stored only in the larval stage, and organic solid wastes such as kitchen waste, food processing waste, livestock and poultry manure and the like can be converted. The black soldier fly larvae have the protein content of more than 40 percent, are rich in unsaturated fatty acid such as lauric acid and the like, are a feed and bait protein source with great potential, and are listed as one of the most main protein feed substitution insects in the future by the food and agriculture organization of the United nations.
The stable egg supply technology is the most difficult point for the large-scale breeding of hermetia illucens, and the light environment for breeding the adult hermetia illucens is a key factor for stable egg supply. After the imagoes are eclosized, the imagoes are mated in 1-2 days under illumination, and the female imagoes can lay eggs after mating for 1-2 days. If the adult insects do not receive proper illumination within the window period of 5 days after eclosion, the adult insects lose the breeding capability. The luminous environment factors influencing the mating and oviposition of the adult hermetia illucens are mainly light quality (spectrum) and light intensity, and the adult hermetia illucens have the best breeding effect under the irradiation of received sunlight based on the environmental adaptation heredity under the long-term natural evolution of species. Although the existing common plastic greenhouse cultivation uses outdoor sunlight as a light source, the cultivation mode is extensive, the light environment is seriously limited by factors such as seasons, weather, geographical positions and the like, the egg laying amount is extremely unstable, and the commercial output value is low. The industrial breeding can provide stable and controllable breeding environment, has high automation degree, and is the mainstream development direction of the black soldier fly breeding industry at present. In industrial culture, the artificial light source is used to replace natural light source, so that natural rhythm disorder can be overcome and stable egg supply can be realized.
There are studies attempting to stimulate adult hermetia illucens to mate and lay eggs using an artificial light source close to the full spectrum or partial spectrum of sunlight, and the ideal effects are not obtained, for example: zhang et al (2010) irradiated black soldier flies with 500W iodine tungsten lamps and only achieved 60% of the breeding effect under sunlight; heusslur et al (2018) adopt a single-color LED, a fluorescent lamp and a tungsten-iodine lamp to irradiate the hermetia illucens, find that the three have no obvious difference on the promotion effect of the egg laying amount of the hermetia illucens, and can not completely replace sunlight; liu et al (2020) use an iodine-tungsten lamp, a metal halogen lamp, a white-ultraviolet LED and a mixed-color LED, and find that the stimulating effect of the former three on the breeding of black soldier flies is inferior to that of the mixed-color LED, but the exact light-quality ratio of the mixed-color LED is not given, and the comparison effect of the light source and sunlight is not mentioned.
Among the above artificial light sources, the iodine tungsten lamp and the metal halogen lamp have high energy consumption, generate heat greatly, and have poor safety to insects with phototaxis, and the fluorescent lamp has short service life and poor stability, and the stroboscopic effect is not favorable for insect breeding. The LED has low energy consumption, small heat generation, strong controllability and customizable wavelength, and is an ideal lamp for completely replacing sunlight in the industrial breeding of the hermetia illucens.
The patent CN107810927A only describes that the combination of the green light of 530-560nm and the yellow light of 580-620nm irradiates the hermetia illucens in a ratio of 1:1, the egg laying amount, the fertility rate and the like are superior to the combination of the green light of 530-560nm and the yellow light of 580-620nm which irradiate the hermetia illucens independently, other wave band lights are not involved, and the light-mass ratio is not optimized; the patent CN108012996A mentions that except for 355-380nm ultraviolet light, 420-470nm blue light and 500-535nm green light, the light of other wave bands is ineffective for black soldier fly, and no specific optimization explanation is made on the light quality ratio; although patent CN110199959A mentions that seven kinds of LED lamp beads of ultraviolet, blue light, green light, red light, yellow light, purple light, orange light and cyan light are used to simulate the solar spectrum and give the lamp bead proportion, it does not mention the respective wave band ranges of various light sources, and the light with the solar spectrum greater than 650nm is actually physiologically ineffective light for black soldier fly; patent CN108386731A describes that 390-435nm purple light, 492-577nm green light, 435-450nm blue light and 2700-3200k warm white light combined LED light has better stimulation effect on mating and egg laying of black soldier fly than sunlight and iodine tungsten lamps, but does not mention the effect of ultraviolet light below 400nm and does not give specific spectral range of the warm white light.
Disclosure of Invention
The invention aims to provide an LED light source for the industrial breeding of adult hermetia illucens and an industrial breeding method of adult hermetia illucens, wherein the LED light source is stable in spawning and high in spawning rate.
In order to solve the technical problems, the invention adopts the technical scheme that:
a LED light source that is used for heisui river horsefly adult batch production to breed, its characterized in that: the LED light source comprises four-waveband light, and the wavelength and the proportion of each waveband light are respectively as follows:
360-10 percent of 370nm ultraviolet light;
440-460nm blue light accounts for 41-50 percent;
510-520nm green light accounting for 32-39%;
and 630-650nm red light accounting for 8% -15%.
The light quality proportion of each light in the LED light source is calculated according to the percentage of the total light intensity of the band light intensity, for example, the total light intensity of the mixed light is 120 mu mol/m 2 The light intensity of the blue light with the wavelength of 440-460nm is 58 mu mol/m 2 And s, the ratio of blue light is 48.33%.
The blue light accounts for 44-46%; the green light accounts for 34-36%.
The ratio of the ultraviolet light to the blue light to the green light to the red light is 1:5:4:1 or 1:10:8: 3.
The total light intensity of the LED light source is 80-200 mu mol/m 2 And s. The total light intensity of the light source is 80-200 mu mol/m 2 The breeding stimulation effect on adult hermetia illucens is good in the range of/s, and the egg laying amount of the hermetia illucens is obviously reduced when the light intensity is lower than or exceeds the range. According to the light source layout of the actual breeding room, the total illumination light intensity can be properly increased so as to meet the requirements that the adult hermetia illucens mainly inhabit and the average actual light intensity of the flying space is in the range.
The light of each wave band of the light source can be uniformly distributed and combined in parallel by adopting a plurality of independent LED lamp tubes or integrated in one lamp in the form of different chip lamp beads. In order to facilitate lamp manufacturing, the ultraviolet LED lamp can be set independently of other three kinds of band light, but the spectrum and intensity of the ultraviolet lamp must satisfy the above description of wavelength and ratio. The light source power supply is a single or a plurality of direct current power supplies, and the power supply power can be matched with the sum of all the lamp tubes (lamp beads).
Compared with the prior art, the invention has the beneficial effects that:
the LED light source consists of four lights, namely ultraviolet light, blue light, green light and red light, wherein the proportion of the four lights is specific. The composition and ratio of light have been proposed by the inventors based on long-term studies. Experimental research finds that the difference of the breeding stimulation effect of the adult black soldier flies is great by the LEDs with different wavelengths and light quality ratios, the photosensitive pigments contained in the pair of compound eyes and the three single eyes of the black soldier flies have the sensing capability on light in the range of 300-plus 650nm, wherein the light sensing peak values respectively appear in the ultraviolet band, the blue light band and the green light band, therefore, the inventor selects the LEDs with different wavelengths in the range of 300-plus 650nm to carry out a great amount of tests such as monochromatic light, combined light and the like, and finds that the change of the light quality components and the proportion has obvious influence on the egg laying quantity of the adult black soldier flies, wherein the best stimulation effect on the mating and egg laying stimulation of the black soldier flies is achieved or exceeded the egg laying effect under sunlight in factory culture to completely replace natural light when the four bands of light with the wavelength of 360-plus 370nm ultraviolet, 440-plus 460nm blue light, 510-plus 520nm green light and 630-plus 650nm red light exist at the same time in a specific ratio, none of the above four bands of light is available. According to the scheme, the proportion of 360-370nm ultraviolet light to 41-10%, that of 440-460nm blue light to 41-50%, that of 510-520nm green light to 32-39% and that of 630-650nm red light to 8-15% greatly improve the mating and egg laying effects of hermetia illucens.
The brightness of the mixed blue light, green light and red light in the LED light source can meet the perception requirement of human eyes, so that an illumination light source manually operated in other aspects is not required to be additionally arranged in a breeding room configured with the light source. The proportion of 360-370nm ultraviolet in the LED light source is only 4-10%, so that the harm to the health of operators is negligible, and the operators can take proper sun-proof measures to enter the breeding room for work.
The LED light source can completely replace sunlight and be used for indoor industrial breeding of hermetia illucens, and can also be used as a light supplement light source in breeding under a light-transmitting condition and be used for supplementing in rainy days or winter when the sunlight is insufficient.
The light cycle of the light source has a remarkable effect of stimulating mating and spawning in the range of 12L (light)/12D (dark) to 16L/8D, for example, the light cycle is 14L/10D when the light source is turned on at 7 am and turned off at 21 pm. Preferably, a time controller can be configured at the DC power supply to realize the self-control of the photoperiod.
The light source can be started to irradiate after a large number of hermetia illucens pupae in each batch emerge into adults, strong holding-to-holding mating behaviors can be observed after 1-2 days of irradiation, and the daily mating occurrence time under the LED light source is looser than the natural rhythm, for example, the hermetia illucens mating holding-to-holding occurs mostly between 10 am and 15 pm under sunlight, while the mating behaviors can be observed at 8 am or 17 pm under the LED light source. If a batch continuous pupa feeding production mode with different growth cycles is adopted, the pupae need to be shaded so as to avoid the interference of a light source on the pupae eclosion process.
Due to the light-emitting principle of the LED, the energy consumption and the heat productivity of the light source are far lower than those of artificial light sources such as a tungsten iodine lamp and a metal halogen lamp, the breeding cost can be saved in the industrial breeding process of the black soldier flies, and the risk of fire disasters or adult scalding caused by contact of the lamp can be greatly reduced. Under the irradiation of the light source, breeding indexes such as egg laying amount, fertility rate and the like of the hermetia illucens are obviously superior to those of a tungsten iodine lamp, a metal halogen lamp, a single-color LED and sunlight, the breeding period of adults can be shortened, and the egg laying production efficiency is greatly improved.

Detailed Description
Example 1: influence of different single-wavelength LED light sources on adult hermetia illucens breeding
The test adopts insect breeding cages of 320mm x 320mm, 50 black soldier fly male and female adults which pupate in the same batch and just eclose in a dark environment within 24 hours are respectively placed in each cage, LED light sources with corresponding wavelengths are immediately started, the irradiation time is 7:00am to 9:00pm per day, the light cycle is 14L/10D, and the light intensity is set to be 100 mu mol/m 2 And s. The light source irradiates the breeding cage at 90 degrees, and the height of the light source from the top of the cage is 15 cm. The test totally investigates the influence of LED light sources with 8 wavelengths on adult black soldier fly breeding by ultraviolet light with three wave bands of 290nm, 330nm and 365nm, blue light with 450nm, green light with 515nm and red light with three wave bands of 650nm, 680nm and 710nm, and each group is provided with 3 repetitions and 24 breeding cages. The LED light source adopts a single-wavelength LED lamp tube.
The breeding environment temperature is 28 +/-1 ℃, and the relative humidity of the breeding environment is 70 +/-5%. Further preferably, in addition to keeping the relative humidity of the breeding environment, water is additionally sprayed into the breeding cages for 3-5 times every day, so that the adult hermetia illucens can be guaranteed to have sufficient water intake. Taking 50% of decomposed wheat bran and 50% of corn flour (mass ratio) as spawning induction information, placing spawning plates at the information, collecting spawns every day and weighing until all groups do not spawn any more. The whole breeding cycle of the hermetia illucens in the embodiment is 8 days.
As shown in FIG. 1, the light of LEDs with five wavelengths of 330nm, 365nm, 450nm, 515nm and 650nm among the 8 wavelengths can stimulate the mating and oviposition of adult hermetia illucens, and the cumulative oviposition amounts in the whole oviposition period are 100.00 + -11.10 mg, 292.33 + -21.58 mg, 422.67 + -18.95 mg, 346.00 + -21.28 mg and 263.67 + -21.05 mg respectively. The light with the wavelength of 290nm, 680nm and 710nm exceeds the sensing range of the black soldier fly visual system, so that the black soldier fly cannot be stimulated to breed, and the cumulative egg laying amount is 0 mg.
This example demonstrates that, in the wavelength range of 300-650nm, which can be sensed by the adult black soldier fly visual system, the LEDs with single wavelength, i.e. ultraviolet light, blue light, green light and red light, can individually stimulate the adult black soldier fly to mate and lay eggs, but the stimulation effects of the LEDs with different wavelengths are different. The light with the wavelength of 290nm, 680nm and 710nm exceeds the sensing range of the black soldier fly visual system, so that the mating and egg laying of the black soldier fly cannot be promoted.
Example 2: influence of LED light sources with different wavelength ratios on breeding of hermetia illucens adults
The test adopts insect breeding cages of 320mm x 320mm, 50 black soldier fly male and female adults which pupate in the same batch and just eclose in a dark environment within 24 hours are respectively placed in each cage, LED light sources with corresponding wavelengths are immediately started, the irradiation time is 7:00am to 9:00pm every day, and the light cycle is 14L/10D.

Wherein, the mixture of three lights of 450nm blue light, 515nm green light and 650nm red light considers 7 different proportions, which are respectively: blue (B) green (G) red (R) 1:1:1, 5:4:1, 1:2:1, 2:2:1, 4:3:3, 1:1:3 and 3:2: 5; a mixture of 365nm ultraviolet light, 450nm blue light and 515nm green light is examined for 3 different proportions, namely Ultraviolet (UV) blue (B)Green (G) 1:1:3, 1:3:1, 3:1: 1; a total of 9 different proportions of 365nm ultraviolet light, 450nm blue light, 515nm green light and 650nm red light are considered, namely Ultraviolet (UV), blue (B), green (G), red (R), 1:1:1:1, 1:10:10:10, 1:10:8:3, 1:5:10:5, 1:5:4:1, 1:5:5:10, 1:5:5:5, 2:1:1, and 3:1:1: 1. The light intensity of each wave band is respectively adjusted by the slide rheostat to ensure that the total light intensity is unified to 100 mu mol/m 2 And s. The light source irradiates the breeding cage at 90 degrees, and the height of the light source from the top of the cage is 15 cm. The LED light source adopts single-wavelength LED lamp tubes which are uniformly distributed and combined in parallel according to the proportion. Each proportion is provided with 3 repetitions, and the 13 wavelength proportions are 39 breeding cages in total.
The breeding environment temperature is 28 +/-1 ℃, and the breeding environment relative humidity is 70 +/-5%. Further preferably, in addition to keeping the relative humidity of the breeding environment, water is additionally sprayed into the breeding cages for 3-5 times every day, so that the adult hermetia illucens can be guaranteed to have sufficient water intake. Taking 50% of decomposed wheat bran and 50% of corn flour (mass ratio) as spawning induction information, placing spawning plates at the information, collecting spawns every day and weighing until all groups do not spawn any more. The whole breeding cycle of the hermetia illucens in the embodiment is 7 days.
As shown in FIG. 2, the 19 wavelength ratios can stimulate the adult hermetia illucens to mate and lay eggs, but the promotion effects are greatly different. When 365nm ultraviolet light, 450nm blue light, 515nm green light and 650nm red light exist at the same time and are mixed according to the proportion of 1:5:4:1 or 1:10:8:3, namely the proportion of the blue light and the green light is about 45% and 36% respectively, the oviposition promoting effect is the best, the cumulative oviposition amount in 7 days can reach 770.67 +/-26.03 mg and 802.4 +/-29.06 mg respectively, the ratio is much higher than that of other wavelengths, and no significant difference exists between the two groups.
This example demonstrates that the difference in the effects of mixing ultraviolet, blue, green, and red lights at different ratios within the visual perception range of adult hermetia illucens (300-.
